IS31AP4991
1.2W AUDIO POWER AMPLIFIER WITH ACTIVE-LOW STANDBY MODE
October 2012
GENERAL DESCRIPTION
The IS31AP4991 has been designed for demanding
audio applications such as mobile phones and permits
the reduction of the number of external components.
It is capable of delivering 1.2W of continuous RMS
output power into an 8Ω load @ 5V.
An externally-controlled standby mode reduces the
supply current to much less than 1μA. It also includes
internal thermal shutdown protection.
The unity-gain stable amplifier can be configured by
external gain setting resistors.
FEATURES
 Operating from V_CC = 2.7V ~ 5.5V
 1.2W output power @ V_CC = 5V, THD+N= 1%,
f = 1kHz, with 8Ω load
 Ultra-low consumption in standby mode (much
less than 1μA)
 65dB PSRR @217Hz in grounded mode
 Near-zero click-and-pop
 Ultra-low distortion (0.025%@0.5W, 1kHz)
 SOP-8 and MSOP-8 package
APPLICATIONS
 Mobile phones
 PDAs
 Portable electronic devices
 Notebook computer
